“Many OEMs offer HDC and hill
assist as part of electronic stability program. Stricter vehicle safety
and stringent emission norms have paved the road for increased adoption
of safety systems in the automotive industry.”

Siddharth Jaiswal, a lead analyst from Technavio, specializing in
research on automotive
electronics sector, says, “Many OEMs offer HDC and hill
assist as part of electronic stability program. Stricter vehicle safety
and stringent emission norms have paved the road for increased adoption
of safety systems in the automotive industry.”

The market for HDC systems is driven by strict regulations mandating
the use of electronic stability control (ESC) in vehicles in developed
regions. In developing regions, governments’ mandates regarding the
installation of anti-lock
braking systems (ABS) will drive the market in the near
future. Connected vehicles use short-range communication to share
information among vehicles and the surroundings. The technology is
expected to extend toward cloud-based platforms to share different
safety and performance system parameters such as HDC, slip angle,
suspension, and vehicle ride characteristics.

The top four emerging trends driving the global automotive HDC marketaccording
to Technavio automotive
research analysts are:

Integration of GPS-assisted cruise control with HDC in HCVs

Growing importance of autonomous terrain profiling and driving system

Emergence of connected all-terrain driving systems

Integration of regenerative braking and HDC in HEVs

Integration of GPS-assisted cruise control with HDC in HCVs

Many luxury car manufacturers have already integrated standard cruise
control with HDC, allowing the driver to manage the
descending speed of the vehicle. HCV manufacturers are focusing on
integrating HDC with predictive cruise control to improve fuel
efficiency in HCVs. The standard cruise control option available in
luxury passenger vehicles helps the vehicle to maintain a set speed
while descending a hill. However, predictive cruise control utilizes GPS
and 3D mapping technology to predict the terrain up to a mile
ahead. Using these inputs, the ECU utilizes the HDC and standard cruise
control to manage the descending speed of the vehicle while maximizing
fuel economy.

“When the vehicle is about to reach the crest of the hill, the engine
braking system is deployed as the vehicle uses its own momentum to climb
the hill. As the vehicle descends down the hill, the system controls the
amount of fuel injected to the engine as per the speed of the descent
and uses HDC when the ECU observes a difference in vehicle speed and
tire speed,” according to Siddharth.

Growing importance of autonomous terrain profiling and driving system

Auto manufacturers are investing heavily in R&D for autonomous terrain
identification and driving. The focus of the auto makers will be to
design a system that can predict the terrain on which the vehicle is
driving. Auto makers like Jaguar use technologies like surface
identification and 3D path sensing, terrain-based speed adaptation,
overhead clearance assistance, and connected off-road convoy in their
terrain prediction and assistance systems.

For surface identification and 3D path sensing, the system
uses the camera, radar, ultrasonic, and LiDAR sensors to analyze the
topology around the vehicle even in adverse weather conditions. The
system uses ultrasonic sensors to identify the surface conditions up to
5 meters ahead of the vehicle. As a result, the system can automatically
change the terrain response settings without the intervention of the
driver.

Emergence of connected all-terrain driving systems

Currently, the connected driving system uses dedicated short-range
communications (DSRC) for vehicle-to-vehicle communications. The
DSRC system uses short or medium-range wireless signals to communicate.
However, inter-device compatibility issues have limited the application
of DSRC for vehicle-to-vehicle communications.

The automotive industry with the help of governments and academia is
trying to standardize the intelligent transportation system norms. The
International Organization for Standardization (ISO) TC204 WG16 is
already in the development stage of setting international standards and
protocols for communications access for land mobiles (CALM).
